Won Hits 17-Year Low as South Korea Seeks to Stem Currency Volatility

The South Korean won has closed at its lowest level since March 2009, hitting 1,549.4 per US dollar. This marks a significant milestone in the currency's decline, with the last time it reached this low being during the aftermath of the Lehman Brothers collapse and the global financial crisis.

The won has been under pressure throughout 2026, breaching 1,500 per dollar in March and creeping towards 1,560 in early June. The current level is a testament to the currency's extreme stress, with foreign investors driving much of the selling. In one session alone, outflows from Korean equities reached $4.6 billion.

The reasons behind the won's decline are familiar: geopolitical tension in the Middle East, a stronger US dollar as a safe haven, and a general mood of risk aversion that tends to punish emerging market currencies first. The South Korean government and the Bank of Korea have committed to monitoring the situation and stepping in against excessive volatility.

The won's weakness has significant implications for investors holding Korean assets. A stock that rises 5% in won terms may not be a win if the currency drops more than that against the dollar over the same period. For crypto market participants, the key to watch is whether won weakness translates into observable shifts in Korean exchange volumes or premium levels.
